Hi, Due to some reason, We are planning to migration solr alone from cloudera search to plain solrcloud 4.10.3 (installed 3 solr and 3 zookeeper alone in baremetal). We are struggling in the migration process. We tried to create/test with one solr collection with same replicas and same no of shards in the plain solrcloud 4.10.3 and copied index data of corresponding shards/replicas to the plain solrcloud 4.10.3 We got with the below error. we were surprised by the below error. because we used same version as we have in Cloudera Search Caused by: org.apache.lucene.index.IndexFormatTooNewException: Format version is not supported (resource: BufferedChecksumIndex Input(MMapIndexInput(path="/opt/solr-4.10.3/node1/solr/sample_collection_shard1_replica3/data/index.20190911092017197/segm ents_4g8h"))): 4 (needs to be between 0 and 3) Thanks & Regards, J. Ganesh Kumar.

Hello, We are trying to migrate the data from Cloudera solr 4.10.3 to plain apache Solr cloud. We didn't find any proper document to migrate seamlessly. Anyone can provide clear documentation on the migration or suggest us the process to follow for the migration. Thanks & Regards, J. Ganesh Kumar.

Problem is due to python version you have in your node. incompatibility between the Python 3 version and the Python 2 version. The default Solr commands use the python2 version, so here we need to remove the Python global environment variables, not the python3 global environment variables. Thanks & Regards, J.Ganesh Kumar.

In oozie shell action I have written code to copy the files from remote server using scp command and I have enabled the password less access to remote server to the user who submit the workflow.
Below are the workflow.xml
<workflow-app name="oracle_log" xmlns="uri:oozie:workflow:0.4">
<start to="scp_copy"/>
<action name="scp_copy">
<shell xmlns="uri:oozie:shell-action:0.1">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<exec>bin/scp-hadoop.sh</exec>
<env-var>HADOOP_USER_NAME=${wf:user()}</env-var>
<file>bin/scp-hadoop.sh#scp-hadoop.sh</file>
</shell>
<ok to="end"/>
<error to="kill"/>
</action>
<kill name="kill">
<message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
</workflow-app>
scp-hadoop.sh
hadoop fs -mkdir /user/{user_name}/dd
scp -r user@xxx:/data/input/ddd.txt /home/{user_name}/

Hi, I have followed the steps from the below document https://www.cloudera.com/documentation/enterprise/5-9-x/topics/search_config_hbase_indexer_for_search.html Upto the topic "Pointing a Lily HBase NRT Indexer Service at an HBase Cluster that Needs to Be Indexed" are fine. I have successfully configured and skipped the topic "Configuring Lily HBase Indexer Security". since I dont have kerberous and sentry enabled cluster. and continued with the next topic "Starting a Lily HBase NRT Indexer Service" Actually I stuck here. How do i start the Lily HBase NRT Indexer Service from cloudera or from machines. When I executed with the below command to verify the current hbase-solr-indexer service status in each host service hbase-solr-indexer status It says "hbase-solr-indexer: unrecognized service" even i checked with jps command sudo jps -lm there is no process in the name of com.ngdata.hbaseindexer.Main I am really confused that the hbase-solr-indexer is one like role instances of hbase service. Thanks & Regards, J.Ganesh Kumar.

Hello pdvorak Thanks for your reply. We have solved this issue by uploading the collections config files back to the zookeeper using update and reload option in solrcloud. After execting those commands we done solr restart. while restarting the solr elects the collection leaders and placed those informations under /solr/collection in zookeeper. Just for my understand could you please answer for the below queries. what do you mean by "zk data dir" . Is it creates the snapshot for the config files in zookeeper. As I know zookeeper holds only the config files instead of data. then what "zk data dir" holds?
